  • Patent number: 8668682
    Abstract: A vacuum regulator apparatus for continuous subglottic aspiration is provided. In one version, the regulator apparatus attaches to a standard vacuum regulator and shares the same vacuum supply outlet as the standard vacuum regulator. Sufficient airflow is provided through the regulator apparatus and calibrated bleed orifice to provide proper continuous subglottic aspiration. Vacuum levels to maintain the airflow are in a range suitable to provide patient comfort. A ball flow indicator provides visual indication of flow through a subglottic tube interface port of the regulator apparatus. A direct flow channel can be momentarily opened causing flow to bypass the regulator module in for clearing blockages affecting the subglottic tube interface port.

  • Patent number: 8670632
    Abstract: Effects of undesired infrared light are reduced in an imaging system using an infrared light source. The desired infrared light source is activated and a first set of imaging data is captured during a first image capture interval. The desired infrared light source is then deactivated, and a second set of image data is captured during a second image capture interval. A composite set of image data is then generated by subtracting from first values in the first set of image data corresponding second values in the second set of image data. The composite set of image data thus includes a set of imaging where data all infrared signals are collected, including both signals resulting from the IR source and other IR signals, from which is subtracted imaging in which no signals result from the IR course, leaving image data including signals resulting only from the IR source.

  • Patent number: 8670891
    Abstract: A passenger in an automated vehicle may relinquish control of the vehicle to a control computer when the control computer has determined that it may maneuver the vehicle safely to a destination. The passenger may relinquish or regain control of the vehicle by applying different degrees of pressure, for example, on a steering wheel of the vehicle. The control computer may convey status information to a passenger in a variety of ways including by illuminating elements of the vehicle. The color and location of the illumination may indicate the status of the control computer, for example, whether the control computer has been armed, is ready to take control of the vehicle, or is currently controlling the vehicle.

  • Patent number: 8671345
    Abstract: Techniques disclosed herein include systems and methods that provide a workflow-based session manager or workflow engine for a content delivery system, such as for delivering video-on-demand, streaming audio, streaming video, etc. Such techniques increase velocity and flexibility of deploying new features and services in a video delivery system. Techniques include a session management model provides a service-oriented and workflow-based approach. As a service-oriented approach, each functional session management step can be represented as a business service. As a workflow-based solution, a sequence of steps to be performed can be defined as data, rather than being hard-coded inside an application. Defined as data, steps (nodes, tasks) can then be created and changed using a graphical editor. New services can be added by defining actions for the new service, and adding a node to a given session management workflow sequence. Techniques include a workflow engine that initiates session management in realtime.

  • Patent number: 8671054
    Abstract: Systems and methods for dynamically managing and netting transactions based on one or more sets of netting rules are disclosed. The present invention dynamically associates transactions with one or more collections based on the execution of netting rules to identify transactions that may be ideal for netting and to perform netting operations and calculations accordingly. The present invention may execute the netting rules according to the priority of the netting rule within a rule hierarchy and utilizes unique solutions allowing for the efficient processing of transactions even as netting rules are created, modified and removed from time-to-time. In addition, embodiments of the disclosed netting system utilize denormalized sets of data and maintain a complete audit trail for all operations.
